OPERATION
SPAN Setting Mode
Your thermostat is set at the factory to cycle at
1˚F (0.5˚C) above and below the set temperature.
(Span = 2) This setting has been designed to pro-
vide a comfortable room temperature under most
all conditions. However, if you find your system
cycling too fast or too slow, then the Span can be
adjusted to modify the cycle time.
■ Press and hold BOTH for three seconds. The display
will flash, and SPAN will be displayed on the LCD.
■ Press to raise the Span to 3. This setting INCREASES
the cycle time by allowing your system to run
LONGER.
■ Press to lower the Span to 1. This setting
DECREASES the cycle time by causing your
system to run SHORTER.
The Span settings remain the same for both HEAT
and COOL.
The Span can be changed at any time, and is inde-
pendent of program times or temperatures.
When batteries are installed in the thermostat, or
the Reset key is pressed, the Span is reset back to
setting 2.
